FAN5665  
High-Efficiency, Adaptive Charge Pump 5V Boost  
Features  
Description  
The FAN5665 is a 5V switched capacitor step-up  
DC/DC converter with an input voltage range from 2.9V  
to 5.5V. Switch reconfiguration and fractional switching  
techniques are utilized to achieve high efficiency over  
the entire input voltage range.
